Its quite out-of-focus, so its not really possible to tell.

Some yes - some no:

That piece is close to a write-off. Why are you trying to salvage it?

Blenko might have been a source of cullet from time to time. Lacking documentation that is just a guess. Cullet's key quality needed to be cost and COE.

Looks more damage than anything....but damage is damage, regardless when or where we speculate it happened.

I think the "O" is a "D".

What is on the surface?

Does anyone know if there was employee migration between Ravenswood and Heaton?

Handmades wholesaled at box of 100 at 20 cents. Simple designs would be 2- or 3 for 1 cent. Better designs would be 1 cent each. Paying more than 1 cent would be considered absurd.

Marbles were easily disposable kid's toys. Machine mades sold for 1 cent - or less. They were produced in staggeringly huge quantities. Identification, grading and value are best and most easily learned at shows where you can handle marbles, look at them from multiple angles, study color, transparency, opacity and variations between same types. Value is driven sharply by type, grading, current popularity, availability and the motivation of the seller. Learning grading from photos is like running a footrace carrying 80 lbs ballast: you could (sort of) - but why try to do it with such a pronounced handicap? Handle enough polished marbles and you can do it as well by feel as you can by vision. You can pick up a HUGE amount of experience and insight in two days (and nights!) at a good show.

Thats interesting in two ways: 1. I never saw anything on the plant slab that would have suggested this. Also - nothing in the office building, the back hill (used lightly as a dump) or the dump area uphill on the road that showed any casting waste. 2. That road to the site is narrow and doesn't seem to be suitable for moving 50 tones of casting each day by large truck. I guess they went out by rail off the spur.

Over a decade ago, I supplied a large amount of marbles to a builder whose client wanted them in a custom kitchen countertop. It has been done - no problem with supply. Owning a swimming pool - you don't want anything but a smooth, continuous pool surface. It would make cleaning a giant pain. Especially in Spring and the height of summer temps.

Place it in a shallow glass of water just covering the piece.
